A Unity plugin, MCP server, and CLI that lets AI agents (Claude, Cursor, Copilot, Gemini, Codex, etc.) build, edit, and playtest Unity games directly from the editor. It exposes 190+ MCP tools for scenes, GameObjects, prefabs, scripting, profiling, and domain extensions, with any C# method convertible to a tool in one line.
Use cases
- let claude or cursor build and edit unity scenes via natural language
- connect an ai agent to the unity editor through mcp
- automate unity playtesting and iteration with an llm
- expose custom c# methods as mcp tools for ai agents
- reduce ai token usage when driving unity from an agent
- generate terrain, tilemaps, cinemachine cameras, or splines with ai
- run an ai develop-and-test loop inside unity
When to choose
- you develop with Unity and want an AI agent to manipulate scenes, prefabs, components, or run scripts
- you use Claude Code, Cursor, Copilot, Gemini, Codex, or any MCP client and want it wired into Unity
- you want to expose your own C# methods as AI-callable tools with minimal code
- you need efficient token usage and local-first operation while iterating on a game
- you want domain-specific tool families like ProBuilder, Cinemachine, Terrain, Tilemap, Navigation, or Timeline
When to avoid
- you work in Unreal or Godot and want the same experience without Unity-specific tooling
- you need a fully free hosted AI agent without bringing your own provider (paid tiers exist for hosted AI)
- you are not using an MCP-compatible AI client or editor
- you need offline operation with no internet access, since the plugin downloads its native MCP server binary on first run
- you require a stable, long-term-supported plugin for Unity versions older than 2022.3 LTS
